This is a magnitude 5.0 earthquake scenario along the Burlington Toronto Structural Zone — a fault near Toronto and its surrounding region. This fault is not known to be active but demonstrates a plausible earthquake scenario for the Toronto region.

In 1997, a magnitude 4.6 earthquake occurred 3 to 4 km beneath the Strait of Georgia, near Vancouver. This scenario visualizes the effects of that event if it occurred today with a magnitude of 4.9. A magnitude 7.0 Georgia Strait scenario is also provided, and represents a less likely but more consequential case for comparison.

Full rupture of the Cascadia interface fault, the fault defining the boundary between the North American and Pacific Ocean plates. This magnitude 9.0 event, often referred to as ‘The Big One’, affects most communities in southwestern British Columbia.

In September 1732 a damaging earthquake occurred immediately beneath the Island of Montréal. This scenario visualizes the effects of that event if it occurred today with a magnitude of 5.0, and represents a strong ground shaking event that could strike Montréal.

This cartographic dataset of areas of importance for spring herring in the Magdalen Islands was produced by Fisheries and Oceans Canada (DFO) and the Magdalen Islands ZIP Committee, as part of the work to characterize the Magdalen Islands Lagoons Marine Refuge. The initiative aimed to document fishermen's ecological knowledge of spring herring, including good fishing areas and spawning grounds around the archipelago. The data comes from interviews conducted between January and April 2024 with the most experienced fishermen in the archipelago. During the interviews, participants identified directly on digital maps the locations associated with four types of observations made throughout their careers: • Question 8 — Good fishing sites; • Question 9 — Other observations of high concentrations of the resource; • Question 13a — Spawning areas and; • Question 13b — Other observations of signs of spawning. To facilitate temporal contextualization, a four-period timeline (before 1996, 1996-2002, 2003-2006, and 2007-2021) was used. The final product is a GeoPackage (.gpkg) containing 16 vector layers composed of four layers per observation type, each corresponding to one of the defined time periods. The polygons were classified according to the number of fishermen who reported each location, making it possible to assess the degree of overlap and the relative importance of the areas over time. The data are projected in NAD83 / MTM zone 4. For more information on the methodology and data, see Burbank et al. (2025). Additional information specific to the Magdalen Islands lagoons is presented in Grégoire et al. (2026).

A magnitude 5.9 earthquake near Montreal, along the Milles-Îles Fault. This fault is not known to be active, but this scenario represents a small but damaging event near the City of Montreal.

Magnitude 5.5 earthquake scenario located directly southeast of Ladysmith Town Centre. This fault is not known to be active, but this scenario represents a small but damaging event near Ladysmith and Burleith Arm.

The National Earthquake Scenario Catalogue, presents the probable shaking, damage, loss and consequences from hypothetical earthquakes that could impact Canadians. It considers only damage to buildings, and their inhabitants, from earthquake shaking, and therefore does not include damage to critical infrastructure or vehicles. Losses from secondary hazards, such as aftershocks, liquefaction, landslides, or fire following are also not currently included. The information is provided at the approximate scale of Census dissemination areas, and is intended to support planning and emergency management activities in earthquake prone regions. This project is run by the Geological Survey of Canada's Public Safety Geoscience Program.

In 1949 a magnitude 8.1 earthquake occurred on the Queen Charlotte Fault, off the west coast of the Haida Gwaii archipelago. This magnitude 8.0 scenario along the Queen Charlotte Fault is slightly different and closer to population centres than the magnitude 7.8 earthquake that occurred in 2012.

A magnitude 5.6 rupture scenario near Ottawa along the Gloucester Fault in the south of the city. This fault is not known to be active, but this scenario is representative of seismicity in the Ottawa Valley.
